Sedimentary - Tectonic Status of Permian - Triassic Boundary (250 Ma) in Gondwana Stratigraphy of Peninsular India

The sedimentary-tectonic status of Permian-Triassic boundary is examined in Gondwana stratigraphy of Peninsular India based on lithofacies characters, palaeoslope, and depositional models. The Late Permians represent meandering streams which flowed from southeast to northwest, except in Damodar basin where palaeoslope was from east to west. In Satpura, and Pranhita-Godavari basins, the Early Triassics record braided stream facies models. The palaeoslope remains northwesterly during Early Triassic sedimentation. ated evidence suggests that the Permian-Triassic boundary in Peninsular Gondwana stratigraphy of India is marked by tectonic discordance, and uplifts in the provenance.
